IMPROVEMENT IN STOP-HINGES FOR TRUNKS, 80C.

Specification forming part of Letters Patent No. 206,226, dated July 23,1878; application filed July 13, 1877.

To all whom it may concern Be it known that I, CHARLES W. BUTLER, of NewYork city, in the county and State of New York, have invented certainnew and useful Improvements in Stop-Hinges; and I do hereby declare thatthe following is a full and exact description thereof, reference beinghad to the accompanying drawing, and the letters of reference markedthereon.

My improved device, which I term a stophinge, is made distinct, but isintended to be used in conjunction with ordinary hinges, to limit theopening movement of a cover or door.

My invention consists in attaching plates to the body and cover of thetrunk orother article to which my invention is applied, to which platesare pivoted arms, which are connected together by a knuckle-joint havinga projecting lip on one arm, which abuts against a face on the lowerarm, by which a stop-motion is given to the cover before it arrives in avertical or upright position, as hereinafter more fully set forth.

In the accompanying drawing, formin g a part of this specification,Figure 1 is a side view of the folding stop in position when open. Fig.2 is a front view of the same.

Similar letters of reference indicate similar parts in the severalfigures.

Gr represents aplate, attached preferably to the inside of the trunk orbox. G represents a similar plate attached to the inside of the cover.To these plates are pivoted the ends of the arms D and D by the bossesor bolts 9. The opposite ends of the arms D D are pivoted together bymeans of the knuckle-joint 0, having the faces d d, which abut againsteach other and limit the opening of the cover.

It will be seen that the lower face or lip d of the hinged arm Dprojects beyond its upper face, so that its projecting end comes in.contact with the face at of the arm D when the cover is raised, and thusprevents the arms D D from being brought in the same line when the coveris raised, thus always maintaining the center of gravity of thetrunk-cover toward the body of the trunk when opened.

Vere the center of gravity of the cover when raised thrown beyond thehinges by reason of allowing the cover to be opened at an angle greaterthan ninety degrees the strain of the weight of the cover would bethrown on the arms D D and the pins 9 g, which is obviated in myconstruction by preventing the cover from ever assuming a verticalposition.

hen the trunk is closed the armsD D fold within the body of the trunk.

The holding-stop above described is used in conjunction with theordinary hinges, which connect the cover with the body of the trunk.

I am aware that arms pivoted to the body and cover of a trunk and toeach other, and provided with a stop at the inner end of one of thepivoted arms, have heretofore been employed, and I therefore lay noclaim to such invention.

What I claim, and desire to secure by Letters Patent, is

The combination, with the arm I), pivoted to the plate G and'providedwith the projecting lip d, of the arm D, pivoted to the plate G and armD, and provided with the face d, substantially as described, and for thepurpose set forth.

In testimony whereof I have hereunto set my hand this 6th day of July,1877, in the presence of two subscribing witnesses.

CHAS. IV. BUTLER.
